Getting started
Here is an example of a typical Warrior Build. STR being the Main Stat followed by END. Feel free to switch the points a little bit around. Starting with INT 4 may be helpful. But let's face it: END/DEF is still the KING at the moment (version 0.29e) in term of reliability. END allows you to survive and make your healing spells (and indirectly your potions) more efficient. Just keep also in mind: AGI 5+ is need to beat the first Boss on his first encounter, with the help of Savescumming of course. STR 8+ allows your MC to beat Hakan and Tomahawk in armwrestling, After the succesful "savescummed" Bossfight we get 5 Lv-Point; that's just enough to gain one stat point right away.
With high STR and AGI it takes around 6-18 minutes to win the fight with Savescumming. If both your STR and AGI are low, it's not worth it, because it will take a lot of time. STR 5 + AGI 5 was the lowest Stats i have ever beaten the Boss and it was a huge pain to do so. [Edit:] It took me around 30+ minutes with bad luck.
Save when the Monster misses you. Reload when the Monster hits you. When you land a powerful crit you may also save. After you beaten the Boss i highly recomend to creat your first "Important Save". Allowing you to play from the start of the game without replaying the fight. Caro implemented a item that does allow you to respec your MC. So there is no reason anymore to start the game with a physical weak MC.
